benchtests: Add random() benchmark
Add a simple benchmark to measure the overhead of internal libc locks in the random() implementation on both single- and multi-threaded cases. This relies on the implementation of random using internal locks to access shared global data, and that the runtime uses multi-threaded locking once a thread has been created (even after it finishes).
